2 Claims, 3 Drawing Figures FOOD WASTE DISPOSER MOUNTING SYSTEM WITH DISHWASHER DRAIN CONNECTION BACKGROUND OF INVENTION The present invention relates in general to the food waste disposer art and, more particularly, to a food waste disposer installation which includes a connection for a dishwasher drain, or the like. Such an installation is shown, for example, in US Pat. No. 2,965,318, issued Dec. 20, 1960 in the name of Hans Jordan.

ln kitchens equipped with a food waste disposer and a dishwasher, it is conventional to drain the dishwasher through the disposer as a matter of convenience, thereby minimizing the plumbing required for the dish washer drain. As disclosed in the aforementioned patent, this is accomplished conventionally by providing the housing of the disposer with a dishwasher drain connection above the comminuting means of the disposer. This arrangement is subject to a couple of disadvantages. First discharging the dishwasher drainage into the metallic housing of the disposer results in considerable noise. Further, some means must be provided to minimize vibration transmission from the disposer housing to the dishwasher drain line, such vibration transmission being an additional source of noise.

CROSS REFERENCE TO RELATED APPLICATION The present application discloses subject matter which is disclosed and claimed in application Ser. No. 160,321, filed July 7, 1971, by Oldrich Fryc and me.

SUMMARY AND OBJECTS OF INVENTION In the light of the foregoing background, a primary object of the present invention is to provide a food waste disposer installation having a very simple means for minimizing vibration transmission and noise resulting from the connection of a dishwasher drain to the disposer installation.

More particularly, an important object of the invention is to provide a food waste disposer installation wherein the disposer is suspended by an elastomeric sleeve which acts in tension and which is provided intermediate its ends with a dishwasher drain connection. A related object is to provide such an elastomeric supporting sleeve for a food waste disposer having intermediate its ends a laterally extending tubular connector to which a dishwasher drain line may be attached.

With the foregoing construction, the elastomeric supporting sleeve for the disposer not only minimizes vibration transmission to the kitchen sink, as disclosed in the aforementioned patent, but also minimizes vibration transmission to the dishwasher drain line. Also, since the sleeve in question is formed of an elastomeric material, the dishwasher drainage discharged thereinto is inherently silenced.

Still another object is to so baffle the interior of the elastomeric supporting sleeve as to further quiet the dishwasher drainage. Such baffling comprises radially inwardly extending baffles formed integrally with the elastomeric sleeve, and a conventional splash guard disposed within the elastomeric sleeve.

The foregoing objects, advantages, features and results of the present invention, together with various other objects, advantages, features and results thereof which will be evident to those skilled in the art in the light of this disclosure, may be achieved with the exemplary embodiment of the invention illustrated in the accompanying drawing and described in detail hereinafter.

DESCRIPTION OF DRAWING DESCRIPTION OF EXEMPLARY EMBODIMENT OF INVENTION Referring to the drawing, designated generally therein by the numeral 10 is a conventional food waste disposer mounted beneath a sink 12 by a mounting system 14 which embodies the dishwasher drain connection of the invention.

More particularly, the sink 12 is provided with a drain opening 16 through which downwardly extends a disposer supporting sleeve 18, preferably of metal, such as stainless steel. The supporting sleeve 18 is suitably sealed relative to the sink l2 and is secured to the sink in the manner disclosed in detail in the aforementioned copending application.

The disposer 10 is suspended from the supporting sleeve l8 by an elastomeric sleeve 20 which acts in tension, with the resultant advantages discussed in the aforementioned patent. Upper and lower connecting means 22 and 24 connect the upper end of the elastomeric sleeve 20 to the supporting sleeve 18, and connect the disposer 10 to the lower end of the elastomeric sleeve, respectively. These connecting means may have any suitable construction. For example, the connecting means 22 is preferably that disclosed in the aforementioned copending application.

The elastomeric sleeve 20 is provided intermediate the upper and lower connecting means 22 and 24 with an integral means 26 for connection to a dishwasher drain line, not shown. The connection means 26 preferably comprises simply an integral, laterally extending, tubular drain connector 28 into which the dishwasher drain line may be telescoped and secured by an external annular clamp, not shown.

The integral elastomeric drain connector 28 inherently minimizes dishwasher drainage noise, and vibration transmission to the dishwasher drain line, which are important features. Further quieting of any dishwasher drainage noise is achieved by baffling within the elastomeric sleeve 20. This baffling includes a radially inwardly extending baffle 30 adjacent the inner end of the tubular connector 28, and another radially inwardly extending baffle 32 on the opposite side of the inner end of the drain connector from the baffle 30, and spaced approximately from the bafi'le 30. The baffling system also includes a conventional inverted frusto-conica] splash guard 34 carried by the elastomeric sleeve 20 oppositethe inner end of the passage through the drain connector 28. The inner end of the passage through the drain connector 28 is inclined downwardly toward the splash guard 34, as shown in FIG. 3 of the drawing.

With the foregoing construction, dishwasher drainage is directed downwardly against the splash guard 34 between the baffles 30 and 32 and the result is that virtually no noise from the dishwasher drainage into the disposer is audible, which is an important feature.

Although an exemplary embodiment of the invention has been disclosed herein for purposes of illustration, it will be understood that various changes, modifications and substitutions may be incorporated in such embodiment without departing from the spirit of the invention as defined by the claims which follow.

I claim as my invention:

1. In a mounting system for supporting a food waste disposer beneath a kitchen sink in alignment with a drain opening therein, the combination of:

a. a supporting sleeve of a size to extend downwardly through the drain opening and having at its upper end an external annular flange seatable on the sink around the drain opening;

b. an elastomeric sleeve having intermediate its ends means connectible to a dishwasher drain, or the like, the latter providing an opening into said sleeve;

c. means for connecting one end of said elastomeric sleeve to said supporting sleeve;

d. menas for connecting the other end of said elastomeric sleeve to the disposer; and

e. a pair of substantially vertical elastomeric baffles on the inner wall of and formed integrally with said elastomeric sleeve, one of said baffles being adjacent said opening and the other of said baffles being circumferentially spaced from said one baffle about said one baffle extending from a level below said opening to a level above said opening, and said other baffle having its lower end at substantially the same level as the lower end of said one baffle.

2. A mounting system as defined by claim 1, including a conical splash guard mounted in the elastomeric sleeve above said opening therein and extending downwardly within said sleeve to a level below the lower ends of said baffles and having a substantial portion of its vertical dimension below the lowermost portion of said opening so that a stream of water entering said sleeve through said opening impinges on one side of said splash guard above its lower end.
